1. Bioscience Research (Main Application)

Standard substrate for cellulase activity testing, serving as a key reagent to evaluate catalytic performance of endoglucanase, exoglucanase and β-glucosidase, and support enzyme screening & biomass degradation studies.

As a carbon signaling molecule, cellotriose induces cellulose-degrading gene expression in fungi and bacteria.

It is also a certified reference standard for qualitative and quantitative analysis of cello-oligosaccharides by HPLC and TLC.

2. Bioenergy Field

It is applied to explore intermediate metabolic pathways of lignocellulosic raw materials such as straw and wood chips for ethanol and biogas production, and optimize enzymatic hydrolysis technologies.

3. Food & Intestinal Microecology

This indigestible oligosaccharide passes through the digestive tract to the gut directly. As a prebiotic, it stimulates the proliferation of Bifidobacteria. Featuring low sweetness and low glycemic response, it can be used as raw material for sugar-free functional foods.

4. Pharmaceutical & Glycochemical Research

It can be adopted to synthesize sugar probes, fluorescently labeled oligosaccharides and drug glycosyl carriers, supporting researches on cellular polysaccharide recognition and intestinal barrier mechanisms.
